Sudden Infant Death Syndrome

Incidence, Epidemiological Factors, Pathologic Findings, Mechanism (pathophysiology), ManagementPrevention

Sudden infant death syndrome (SIDS) refers to the sudden unexpected death of an infant under the age of one year who prior to the event was considered to be completely healthy. The diagnosis also requires that a review of the clinical and environmental history, death scene investigation, and autopsy fail to reveal an alternative explanation of the death. In other words, the diagnosis of SIDS remains a diagnosis of exclusion.

Although a definitive cause of SIDS remains unknown and there are no methods to predict which infants will die from SIDS, parents should be educated about strategies that will lessen the likelihood of a SIDS event. Parents should be advised to place infants on their backs for sleeping, provide a firm mattress, avoid loose clothing and blankets in the crib, avoid overheating their infant, breast-feed, and take their infant for regular medical care.
